About Peanut Butter Banana Muffins

This may or may not be the third banana muffin recipe that I have shared on my website. What can I say? We like banana muffins. The first was Cinnamon Swirl Banana Muffins that have been a total hit and are one of the most popular recipes here.

The next was Banana Cream Muffins that are not only packed with banana flavor, but have a cinnamon cream center. They are absolute heaven.

As long as we’re talking about bananas, you’ve got to try this Cake Mix Banana Bread. It is seriously one of the easiest recipes I’ve ever made, and the result is delicious. You’ll also want to try these delicious Banana Pancakes. Now on to the recipe!

Peanut Butter Banana Muffins

These muffins have quickly become a favorite at our house. They are great because you can add things to them like chocolate chips, white chocolate chips, nuts, etc. Or you can make them without and they are just as good. We like to add some milk chocolate chips and call them Chunky Monkey Muffins!

Ingredients for Peanut Butter Banana Muffins

*Ingredient amounts are located in the recipe card at the end of this post.

• Butter: You will need softened butter for this recipe. Both unsalted and salted butter will work Using butter creates a moist muffin and contributes to their delicious soft texture. To soften butter, remove it from the refrigerator and let it come to room temperature, or soften it in the microwave.
• Sugar: Regular granulated white sugar works great in this recipe.
• Brown Sugar: Brown sugar is used alongside white sugar because it tends to make baked goods, like these banana muffins, more moist.
• Eggs: I recommend using large eggs for this recipe.
• Mashed Bananas: This muffin recipe is the perfect way to use up over-ripe bananas.
• Creamy Peanut Butter: My family prefers creamy peanut butter, but if you want a little crunch with your muffins, feel free to use crunchy peanut butter.
• Milk: I usually use 2% milk when making these muffins. You can easily substitute higher fat milks or almond milk.
• Vanilla Extract: I love to use pure vanilla extract because it really enhances the flavor of these muffins.
• All-Purpose Flour: I use all-purpose flour to make these Peanut Butter Banana Muffins because it is so versatile.
• Baking Soda:Baking soda is used in this recipes as a leavening agent to help the muffins rise.
• Salt: This is used in baked goods to enhance sweetness.
• Chocolate Chips are optional. Dark chocolate chunks are also a great option.

Step-By-Step Instructions

[Step 1] Cream the butter, sugar, and brown sugar until light and fluffy in a medium bowl. I like to use my food processor for this step.

[Step 2] Add the eggs, one at a time, mixing after each addition. Beat in the mashed bananas, peanut butter, milk, and vanilla extract.

[Step 3] In a separate bowl, use a whisk to combine the flour, baking soda, and salt. Add the wet ingredients to the dry ingredients and mix until moistened.

[Step 4] Gently fold in the chocolate chips, if desired.

[Step 5] Place paper muffin liners in a muffin pan or spray each cup with cooking spray. Use a cookie scoop to add about ¼ cup of batter to each muffin cup.

[Step 6] Bake at 350 degrees for 14-16 minutes or until a toothpick placed in the center comes out clean. Allow the muffins to cool on a wire rack.

How to Store Muffins

To store leftover peanut butter banana muffins, let them cool completely, then pop them into an airtight container or zip-top bag. You can keep them at room temperature for up to 3 days, or if you want them to last longer, store them in the fridge for up to a week.

For a quick reheat, just pop a muffin in the microwave for about 10-15 seconds to bring back that fresh-from-the-oven warmth. If you prefer a crispier texture, heat them in the oven at 350°F for 5-10 minutes.

Baking Tips & Tricks

• Use Overripe Bananas: The riper, the better! Overripe bananas are sweeter and give the muffins a rich banana flavor.
• Creamy Peanut Butter Works Best: For a smooth texture, use creamy peanut butter instead of crunchy. Natural peanut butter can also work, but be sure to mix it well before using.
• Don't Overmix the Batter: To keep your muffins light and fluffy, gently fold the ingredients until just combined. Overmixing can make the muffins dense.
• Toss Chocolate Chips in Flour: To prevent the chocolate chips from sinking to the bottom, toss them in a little flour before adding them to the batter.
• Adjust Sweetness: If your bananas are super sweet, you can reduce the amount of added sugar to balance the flavors.
• Add a Crunchy Topping: Sprinkle a mix of oats and a little brown sugar on top before baking for a delicious crunchy topping.
• Test for Doneness: Check if the muffins are ready by inserting a toothpick into the center. If it comes out clean or with a few moist crumbs, they're done!
• Cool in the Pan for 5 Minutes: Let the muffins cool in the pan for a few minutes before transferring them to a wire rack. This helps them firm up a bit and makes them easier to remove.
• Freeze for Later: These muffins freeze well! Just wrap them individually in plastic wrap and place them in a freezer-safe bag for up to 3 months.

Frequently Asked Questions

• Can I use crunchy peanut butter instead of creamy? Absolutely! If you're a fan of a little extra texture in your peanut butter banana muffins, feel free to swap the creamy peanut butter for a crunchy variety. The outcome will be just as delicious, adding a nice crunch to each bite. You can use any type of peanut butter you'd like, even natural peanut butter, almond butter, or cashew butter.
• What if I don't have overripe bananas? Overripe bananas are ideal for these muffins because they add natural sweetness and moisture. However, if you're in a pinch, you can ripen bananas quickly by baking them in the oven at 300°F for about 15 minutes, or until they're blackened and soft.
• Are these muffins suitable for a quick breakfast or an afternoon snack? Yes, these peanut butter banana muffins are perfect for a quick grab-and-go breakfast or a satisfying afternoon snack. Wrap them in plastic wrap for an easy on-the-go option, ensuring you always have a delicious and nutritious treat at hand.
